30 Tons Overhead Crane Core Features

30 Cần cẩu tấn

Các 30 tons overhead crane integrates advanced engineering, safety design, and user-friendly functionality, with the following key advantages:

1. Thiết kế kết cấu mạnh mẽ: The main beam and end beams are fabricated from high-strength Q345B steel, undergoing strict welding and heat treatment processes. This ensures excellent load-bearing capacity, khả năng chống biến dạng, and long-term durability even under frequent heavy-load operations.
2. Comprehensive Safety Protection: Equipped with multiple safety devices to eliminate operational risks:
- Overload protection device: Automatically cuts off power when the load exceeds 110% of the rated capacity, preventing structural damage.
- Upper/lower limit switches for hoisting: Stops the hook from overtraveling, avoiding collisions with the crane frame or ground.
- Emergency stop button: Enables immediate shutdown of all mechanisms in case of emergencies.
- Anti-sway system: Reduces load swing during movement, improving positioning accuracy and preventing load damage.
3. High Operational Efficiency:
- The hoisting mechanism adopts a high-torque variable-frequency motor, supporting stepless speed regulation (0.8-8 m/min for hoisting, adjustable based on load weight).
- The crane (longitudinal travel) and trolley (transverse travel) mechanisms use precision gearboxes and rail clamps, ensuring smooth movement and positioning accuracy within ±5mm.
4. Hệ thống điều khiển thông minh: Adopts PLC (Bộ điều khiển logic lập trình) with a touchscreen HMI (Giao diện người-máy). Operators can monitor real-time data (load weight, travel speed, giờ làm việc) and adjust parameters easily. Remote control is optional for scenarios requiring long-distance operation.
5. Bảo trì dễ dàng & Low Downtime: Thành phần chính (động cơ, reducers, vòng bi) use internationally renowned brands (VÍ DỤ., Siemens, ABB) for reliable performance. The crane is designed with accessible maintenance hatches and lubrication points, simplifying routine inspections and reducing maintenance time.

Difference Between Single-Girder & Double-Girder 30 Tons Overhead Cranes

30 Cần cẩu tấn

Double girder overhead crane

While both models handle 30 tấn, their structural designs and application scenarios differ significantly. The following table compares key aspects:

Thứ nguyên so sánh	Single-Girder 30 Cần cẩu tấn	Double-Girder 30 Cần cẩu tấn
Structural Design	Single main beam (I-beam or box beam) supported by end beams.	Two parallel main beams (box beams) connected by crossbeams.
Span Adaptability	Maximum span ≤ 22 m (limited by single-beam load-bearing capacity).	Maximum span ≥ 31.5 m (suitable for large workshops/yards).
Nâng chiều cao	Nói chung là 6 - 18 m (limited by trolley installation space).	Nói chung là 10 - 30 m (more vertical space for trolley movement).
Space Occupancy	Lower headroom (saves workshop height); smaller overall size.	Higher headroom (requires taller workshops); larger footprint.
Operational Stability	Moderate stability (prone to slight beam deflection under heavy loads).	High stability (dual beams distribute load evenly, minimal deflection).
Load Frequency	Suitable for medium-frequency operations (≤ 1,500 cycles/year).	Suitable for high-frequency operations (≥ 3,000 cycles/year).
Cost	Lower initial cost (30% - 50% cheaper than double-girder).	Higher initial cost (but lower long-term maintenance costs for heavy use).
